Product Description

The Relay & Contact Sensor-6 (RCS-6) is a flexible tool to build a Control4 system more effectively. It combines the capabilities of a repeater and router with 3 contact inputs and 6 relay outputs.

The repeater function allows more devices to be joined to the network, and provides more coverage for a ZigBee mesh network. The RCS-6 contains a new high power radio module and can support up to 16 child nodes.

What Is Included

  • RCS6 Relay Contact Sensor
  • Terminal Blocks
  • Power Supply


Before mounting, make sure the device is in a location where you can still push the button to join it to the ZigBee network. If the location will be difficult to reach, view the instructions for ZigBee networking and join the device to the network before mounting.

The RCS6 has two holes for screws on either side of the device. Depending on wall material and location, consider using a wall anchor. Distance between screws is 4.5” center to center.

Mount the device snugly to the wall.

Contact Wiring

The 6 Pin jack provides 3 contact sensor inputs. Contact sensor inputs are for dry contacts only.

  • Contact 1: C1 & Com
  • Contact 2: C2 & Com
  • Contact 3: C3 & Com

Relay Wiring

6 Relay outputs with terminal blocks. Relay connections are not polarized.

  • Relay 1: R1 & R1
  • Relay 2: R2 & R2
  • Relay 3: R3 & R3
  • Relay 4: R4 & R4
  • Relay 5: R5 & R5
  • Relay 6: R6 & R6

Relay Specs

DC Load on Relay:
Max current = 1A
Max voltage = 60VDC
No Polarity

AC Load on Relay:
Max current = 1A
Max voltage = 40VAC
No Polarity

Power Input

Alternative to the 3.6V plug-in power supply, you may supply power by connecting 6.5-24V lines to the P1 and P2 terminals, not polarized.

8 tap to enter setup. When in setup, 1 tap to toggle between modes. Test Contacts and Relays Mode will respond with 1 flash and Test Communication Mode will respond with 2 flashes. Setup mode can also be entered through property setting in composer.

Test Contacts and Relays Mode: LED flashes to display state changes (see table on next panel). In this test mode, when a contact is closed the relay of the same number (ex contact 2 and relay 2) is also closed, when contact opens, relay opens.

Relay states can be changed by adjusting properties in composer. Relays can be triggered through programming in composer and or proxy binding connections.

Test Communication Mode: Every 7 seconds the device sends a message to the controller, if it receives a reply the LED will flash. More flashes mean a stronger signal. A measurement of signal strength is printed in composer. Set property Debug Mode to Print and select the Lua tab to view signal strength (measured from the last message the device received before sending its comm test message). This message can be from anything communicating with this device including other devices that are using it as a router. Most likely the last message will be from the controller since the controller replies to the comm test message every 7 seconds.

If the device doesn’t power up make sure you are using the suggest voltage and your power supply is outputting voltage.
To determine if the device is connected to the network unplug the power source and watch the LED while plugging it back in. If LED flashes the device is not joined, if the LED shows 1 long solid flash the device is joined to the ZigBee network.

Check wiring and connections. If they are correct then there may be a problem with the device.

This driver supports the RCS6-C4ZB-21

The device has to be mounted within the range of the ZigBee network in which it is to operate.

Network range will vary depending on the strength of the router it is connected to, as well as physical obstructions. Typically the device can communicate up to 400 feet in the open , however range will be significantly reduced indoors. Ensure the network is designed properly and that router strength and physical barriers are considered.

Button Presses:

Join: 4 taps – 6 flashes – Long solid flash when joined
Leave: 13 taps – 6 flashes
Setup: 8 taps – 1 flash
Reset: 15 taps – 6 flashes if not joined or long solid flash if joined
